Heart Structure & Double Circulation
Describe the structure of the heart (four chambers, valves, coronary arteries) and explain how it pumps deoxygenated blood to the lungs and oxygenated blood to the body in a double circulatory system
Suggested ages 12–13
Evidence of understanding
- Labels a diagram of the heart showing atria, ventricles, valves, aorta, vena cava, and pulmonary vessels
- Traces the route of blood through the double circulatory system
- Explains the role of valves in preventing backflow
- Compares arteries, veins, and capillaries
Assessment prompt
If Heart Structure & Double Circulation felt their heartbeat, could they describe what the heart is doing — explaining the two sides of the heart, where the blood goes from each side, and why we need a double loop?
